91 octane on 93 octane program
For the last couple of weeks I have been running the 93 tune on 91 gas. I'm not experiencing any problems how the truck runs, but have noticed it runs hotter. My normal running temp is 196 on average, and previously have never seen over 200 on the ECT. (Its gone as high as 208) I plan on taking back to level 1 tune today, but was wondering if the higher octane is causing the temp increase or the tune? If I am still running hot after going back to level 1, I will take the truck in to be checked out. When I originally ordered the Gryphon I asked for level 2 to be for towing, and level 3 performance, but here is southern Calif I can't find any 93 octane. Do I need to have a program for 91 instead of 93?
